Transform your existing Fox 36 suspension fork into the ultimate trail fork. The ACS3 coil conversion kit combines small bump sensitivity, traction, and mid stroke support of a coil with the big hit performance of an air spring. By using coil springs, you can eliminate the constant maintenance required to keep your fork running optimally!

- Reduced friction for smoother overall fork performance
- Air Bump Stop cartridge technology to control the bigger hits towards the end of the travel
